To allwhom t ma concern:

Be itknown t at l, ORRELL Asrrronga citizen of the United States, residing. at Swampscott, in the county of Essex and `State of Massachusetts, have invented certain Improvements in Assembling-Machines, of which the following description, 1n connection with the accompanying drawings, is"

a specilication, like reference characters on the drawings indicating like parts 1n the several figures.

This invention relatesto'machines for asf semblingparts of boots and shoes.

The invention is herein shown yand described as 'embodied' in"a`machine of the type described in United StatesLetters Patr ent No. 1,026,940, granted May 21, 1912. It will be understood, however, that the in-l vention is not restricted in all its features to embodiment in a machine of the particular type described in the said patent. The

machine of the said patent has provision for v inserting a fastening in the rear-face of a last, at a point removed from the sole, for the purpose of securinga shoe upper to the last. The machine also includes devices for wiping the upper over the edge of the last` arid for pressing the upper into close en-- gagement with the last adjacent to the sole,

and means for securing the wiped-over iup-- per to 'an insole mounted upon the last. It

'is very desirable that the upperbe smoothed out and drawn closely to the form of the rear face ofthe last before being secured thereto, since the appearance of the shoe and, particularly in the case `of a low shoe, its fit and comfort are largely dependent upon its shape at the heel end.

An important feature of the invention accordingly consists in the provision, in a mav chine for operating upon the upper at the heel endl of a shoe, of means, operating toward the cone of the last, to place theupper under tension. The preferable arrangement of mechanism comprises a wiper which-I moves downward in engagement with the rear face of the shoe simultaneously with' the forward movement of the devices previously referred'to, which wipe the upper over the edge of the last. By the action of such mechanism the upper is smoothed out and pressed closely into conformity with the last. It isnot essential that the oppositely acting tensioning devices operate simultaneouslyi they may be timed to act successively, each performing its function while .for good results, that the Work be very close to or in actual engagement withl the fastening inserting mechanism, a condition'which is dicult to bring about .when the said mechanism consists of 'vertically spaced, sta

tionary tackers, since the sizes and vertical curvatures of the rear ends of lasts are s0 various that an arrangement that .'would fit one last would be totally unsuitable for another.

Another feature of the present invention, therefore, consists in fastening inserting mechanism constructed for adjustment'to various sizes and styles oflasts.

It is preferable 'that the adjustment ybeautomatically eifected and, in the embodiment of the invention hereinafter described, the mechanism comprises separately movable tacking devices coperating with an equalizing lever so that they automatically adjust themselves to the curvature of the face .of the shoe brought into engagement with them. Provision is also made for varying the spacing between the fastenings 'for lasts of different' heights and the provision of means for drawing the/work firmly into engagement with the tacking devices and locking it in this position during their operation is also contemplated as a of the invention.

A further 'object is vto provide lfor the correct vertical location of the shoe relative to the various Operating devices. This is best feature l as a done by reference to the sole and a stop is therefore provided, against which the sole may bev positioned. Means, comprising a system of levers or an equivalent 'coperating with' the shoe supporting jack, is provided for raising the jack automatically as itis moved inward and for. pressing the sole yieldingly' against the stop. It is also pres ferred to lock the jack againstdepression during the further operation ofthe machine although this is not indispensable. In the illustrative machine .herein described the locking is automatically accomplished by a In the present machine the wiper which operates toward the cone of the last has cor bined with it a tack driving mechanism. When such a construction is employed, it is particularly desirable that the return movement of the wiper shall not occur until'after the removal of the shoe, since the tack is .only driven part way into the work and return movement of the tack block in engagement with the shoe would bend the tack or pull it out. l

Another feature of the invention, accordingly, comprises a wiper which is power operated for forward wiping movement and which has its return movement under the control of the work support so that'the return movement of the wiper does not take place until after the work hasbeen removed.

Another feature of the invention consists in a reciprocatingwiperand means coperatng with the wiper to effect pulling of the upper ahead of the wiping face of th'e wiper as the Wiper is' advanced. As shown, a reciprocating wiper is provided ywhich moves horizontally over the work, and means is located in front of the wi er which cooperates wth the end face o the wiper in seizing the flange of upper projecting above the wiping plane. Preferably relative separation of the wiper and the seizing means is effected when the wiper is retracted to permit insertion of the upper, the seizing means being rendered effective to seize the upper as the wiper advances and acting to pull the upper ahead of the wiping face ofthe wiper.

Other features of the invention, including details of construction and combinations of parts, w'll be hereinafter described and defined in t e appended claims.

Referring now to the drawings: 10 indicates a suitable base or frame upon and in which the operating parts of the mechanism are mounted. At the front lower portion of the frame a. jack support 12 is pivoted at 14 for movement toward and from the machine. The upper portion of the supporting member 12 is hollow to permit the pas-- sage therethrough of the lower end of the jack post 16, as shown in Fi 5. A collar 18 is formed upon the jac post and is adapted to rest upon a frame 20 to limit the downward movement of the post in its support. The frame 20 is adjustably fitted to the upper end of the supporting member 12 in a manner to be described hereinafter.

Referring now to Fi s. 4 and 5, a lifting lever 22 is pivoted to t e base 10 at a point 24 near the oint 14 aboutwhich the jack turns. The orwardly projecting portion of the lever 22 is bifurcated as shown at 26, 28. The arm 28 is arranged for engagement with the lower end of the jack post 16 to elevate the latter in a manner to be described. A controlling lever 30 is pivoted between its 'ends to the member 12 and carries at its lower end a roll 32 which rides upon the upper 'face of the arm 26. The upper end of the' controllin lever 30 is connected bya link 34 to the ase 10. At the u per end of the lever 30 is also mounted a. b ook A36 with which a` stop 38 upon the member 12 is arranged to cooperate to limit It will be apparent that as the jack is swung outward from the position shown in Fig. 4 the movement of the pivotal point 40 of the controlling lever 30 will cause, the. lever to swing about the point 42 as a center and, consequently, the roll 32 will .also swing outwardand downward. Inasmuch as the roll 32 is atthis time in engagement with the arm 26 the latter'wll be depressed, lifting the weight,44.uponlthe inner arm of the lever 22, and permittingthe jack post 16, the lower end of which rests upon the arm`28, to` descend .until the lcollar 18 rests on the `frame`20. A hook 46 is pivoted in 120 the frame 10 at a point 48 above the lever 22. The hook-16 is provided with a" block 4.9 arrangedfor engagement with a" stop surface 50 uponthe frame 10 as a final limiting means for downward movement of the 125' hook.V A spring 45, Fig. 7,coiled about the "ivot 48, tends to force the hook'downward. he.' frame 20 is fitted to the top of the member 12 ina manner tozpe'rmit forward .ind rearward adjustment byx'means of the 13 the outward swinging movement of the jack.

frictio'n upon it a cam face 58 adapted for operativeV engagement with the roll 56. The formation of the cam surface'58 is such that as the hook descends the .roll 56 will be moved rearward and the jack will be drawn into the machine. The lever-46. projects rearward from the pivot 48 as represented at 60 and the rearward projectionis connected by'a rod 62 to a4 bell crank cam lever 64 pivoted at 66 to themachine frame. The

in ups'tnding arm 68 ofthe cam lever carries a into coperative relation to ,of the machine.

80 onthe machine and holds the pawls roll arranged for operative engagement with a cam' 72v upon the main drive shaft 1 The arrangement is such that when the stopped position, as shown in Fig roll 70 is on the highest part of the cam 72 a'nd'vthe connecting rod 62 is consequently depressed, raising the hook 46 to permit the jack-to swing forward away from the machine. `The 'lower end of the r'od 62 carries 'a projection 74 having a cam face 76 ar,- ranged for engagement with the upper ends of a p air of pawls 78 whichare'pivoted at frameu .Spring pressed plungers 82 tend to press the ower ends of the pawls 78 into engagement with a Segmental ratchet 84 upon the rear end of the lever 22. When the machine is in its stopped position the projection 74 engages with the ratchet 84, permitting the lever 22 to be moved at will. When the jack is swung into position to bring the last86 the operating parts of the chine, as showny in Fig. 2, the heel end .of t e sho'e upper carried on the last engages and is definitely located by tvv.` V-shaped tack blocks 88, 90.

Referring to Fig. 11, each oflthe tack blocks forms part of a slide 92. The slides 92 are mounted for movement longitudinally in suitably formed guideways 93 (see Fig. 12). At the forward end of each slide 92 a laterally projecting lug 94 is arranged in coperative relation to a spring pressed plug 96 which tends to move the slide and the tack block 88, formingla part thereof, forward. An equalizing lever98, Fig. 14,

is pivoted at 100, its ends being located tok he engaged by the rear ends of the slides 92. this .arrangement the rear end of the shoe maybe seated iirmly in botlrV blocks, which automatically7 adjust themselves to the work, irrespective of the curvature of the rear end of the-last.'4 Iffit be not desired to utilize the automatic equalizing feature, rearward movement of one 0r both e slides 92 may be prevented by turning the flat sided thumbnut 102 through part of'a revolution to bring its rounded machine is in its normal 2, the

B mg the adjusting screw112, Fig. 11, adj ust` ment of the tack I driver` about the bolt 108 as a center is permitted,*rfter which the bolt may be tightened tohold 1the mechanism in its adjustedposition.y The lower V block 90 and its tack driver are carried by a vertically movable slide 1.14, Fig. 12. The slide 114 is connected'b. a T slot' and guide to a vertically-adjustab e4 slide 116, which in turn is connectedbyafT slot and guide to a third slide 118. The upper V- block 88 is carried by thel intermediate slide 116. A asses through all the sliding members an through a slot 122 in the Wing 124 which forms apart of the frame of 'the machine. The bolt is held from rotation by slot in the slide 118. A clamping nut 126 is'integral with a hand le'ver 128 and the parts are so arranged' that upon the nut 126 its rear face is slidably arranged in a groove 134 in the wing 124 and rests in a corresponding groove in the. slide 118, as'clearly shown in Figs. 6 and 12. A shaft 136 has a pinion 138 upon its inner endan'd hand wheel 140 secured to its outer end. The pinion 138 meshes with the rack 132 and, since the shaft lr6 is journaled in the Wing 124 of the frame, rotation of the hand wheel willefect vertical adjustment of the rack bar 130. The bolt 120 acts as a dowel to prevent relative vertical movement between the slide 118 and the bar 130.' The slide 118 vertical adjusting the rack-bar. A. threaded into the uponits inner end movement imparted to clamping screw 142 is slide 116 and has formed a head 144. A collar 14 is pinned to the outer end of the screw, the space between the head and the collar being somewhat greater than the combined thickness of tlie slides 114, 116 and 118, as'is clearly apparent in Fig. 12. The screw 142 passes ythrough slots 148 and 150 inthe slides 114 and 118, respectively.

By reason ofthe construction just de` scribed, rotation of the screw in one direction will cause its head 114 to clamp the a" spline-125 located in a slide 1 18 to the slide ,116, while' rotation of the screw in the opposite direction will cause the collar 146 to operate to'clam the slide114 to the slide A116. Thus it will be shown in Fig. 12, a reduced portion 156fot` responding gibs`248. 250 on the carriage 216,`

,A `...Ii` The operationof the machine heretofore described is as follo`ws:The shoe parts, which usually comprisev an insole and a lined upper having a counter inserted between the upper and lining, having been arranged upon a. last, the last is placed upon the Ypin 280 =and the jack is moved toward the machine until the heel portion of the shoe. is

l seated'inv Athe V Vblocks 88, 90 which act as .gages to locate the shoe accurately. As the jack moves inward the controlling lever 30 swings about its pivot 42, causing the roll 32' to be raised and permitting the weight 44 todescend. This causes the arm 28 of the lever 22 to rise, whereby the jack post is elevated yieldingly. When 46 about the pivot 48. The cam 58 coperates with the cam roll 56 to draw the work.

firmly into the V blocks which automatically adapt ythemselves to thecontour of' the heel end of the last by reason of the equalizing' lever connection 98. If the lower V block has any tendency to drag the. upper downward on the last, the pin 100 may be placed vin the upper hole 101, Fig. 14, making the lower arm of the equalizing lever 98 longer vthan the upper arm, with the result that the stationary V block 88 will exert considerably more pressure upon the work than the wiper block 90, and will hold the work securely to the last during the operation of the said wiper block. As the rod 62, which'is con.- nected to the rear end of the hook 46, rises, the projection 74. is disengaged from the pawls 78, one of which engagesa tooth of the ratchet 84 to lock the jack against deprcssiom T-he wiper carriage 216 now starts forward, the wiper 258 engaging the edge of the upper and wiping the upper, counter and lining over the edgevof the last. The spring pressed plunger 252 permits the wiper l carrier 240 to lthis time the spring 306 and p any desired :torin` which operatesV the parts have reached-y approximately the position shown in Fig. 4,

At pin 182 is at the rear end of. the slot 184, the link 176 being held forward and the weight of the slide.114 and the parts carried thereby spring pressed plug 196 bearing upon the eccentric cam surface 262. moved rearward, simultaneously with the forward movement of the' wiper, through the lever 178 which is connected at 242 to the wiper carriage. Assuming the slides 116 and may ride up .118 to be clamped together, rearward move ment of the link 176 .operates through the scribed to ower the slide 114 which carries being sustained by the.

The link 17e is The block ,90 at this time performs a wiping' action upon the shoe upper 1n a direction op' posite to the .direction'of action of the wiper 258, with the result that 'the upperv is stretched tightly. and smoothly over the heel of ,the-last. Since-the wiper carrier rises Asomewhat whengthewiper passes over the .edge ofthe last,"the stop 4V moves away wiper. moves forfromthe work. As .the

ward, the presser 260 presses face of the upper and assists in forming al well defined edge at the heel. When the vwiper 258 has reached theforward limit of its movement the tacker 288 operates t0 drive a fastening into the work. The drivy ing mechanisms 190, if not out out,.also operate at this pointto drive one or more tacks into the face of the upper. During further rotation of the driving shaft the cam 272 causes the block 266 to be raised, elevating the wiper 258 until it is out of contact with the work, whereupon the wiper 258 returns, Vbeing maintained til it has reached the rear limit of its stroke. During the return stroke of the wiper the pin 182 moves forward in the slot 184. The plug 196 at this time bears upon the concen` tric cam surface200 and has no tendency to move the link 176 forward. The cam 7 2 now .causes the rod 62 to descend, raising the hook 46 an'd unlocking the pawls 78 to per-v mit the jack tofbe drawn away from the machine and lowered. As the -jack is-jdrafwn forward the lever 22 is raised* v the rod 204 and spring 212 thelink 176 is moved forward and the lowervV block 90 is raised to its original position. This taking place after the shoe has been removed from the block, there is no danger of the tack being disturbed or the work beingmarred by upward movement of the block in Contact with it. At the `endofthe return .move-A ment of the'wiper, the cam 272 permits it to descend, so that it is in its initial position when the machine stops.

Adjustment of the height at which the upper tack is driven into the counter may in its elevated position unandA .through be effected after loosening the clamping nut 126 by rotation ofthe hand wheel 140 which, through the rack and pinion 132, 138, will raise or lower the rack bar 130. The slide 118 will partake of the movement of the bar 130fas will the slide 116 which is clamped to theslide 118 by the screw 142. The parts described are secured in adjusted position by tightening the clamping nut 126. If it be desired to adjust the spacing between the u per and lower tack blocks 88, 90 this may b in diierent holes 174 whereby the vertical adjustment of the slide 114 relative to the bell crank lever 162 is changed. The length of stroke of the lower tack block 90 may be varied by vertical adjustment of the fulcrum 1,80 which is mounted in a slot in the machine frame for that purpose, as is shown clearly in Fig. 1. Since the stroke of the wiper carriage, and the pivot 242 carried thereby, is constant, variation in` the position of the fulcrum 180 will vary the stroke of the pin 182 and, consequently, the stroke of the tack block 90. In case it be desired to move both blocks 88, 90 downward to effect a wiping operation the slide 116 may be secured to the slide 114 by turning the screw 142 in the opposite direction from that previously described, whereupon the slide 116 will be released from the slide 118 and the V blocks 88, 90 will move together, such movement being permitted by the slotted connections 150, 152, 154. Sometimes it may be desirable to dispense with the equalizing movement of the tack blocks 88, 90. For example, when operating upon small shoes it may be convenient to use only one of` the said tack blocks. Provision has, therefore, been made for preventing equalizing movement of the blocks by turning the thumb nut 102 until it rests back of the shoulder 104 and prevents its corresponding block from yielding rearward. When it is desired to adjust the position laterally of the shoe at which the tack is to be driven into the face of the shoe in order, for example, to avoid a seam, the bolt 108 is loosened and the adjusting screw 112 manipulated until the desired adjustment is secured after which the bolt 108 is tightened to maintain the adjustment.

Instead of constructing the stop 274 as described, :reconstruction such as illustrated in Figs. 15 and 16 may be employed. A combined `stop and gripper jaw 320 is'carried at the lower end of a gripper lever 322. The lever 322 is pivotally supported at 324 in a bracket 326 carried by the wiper carrier 240. A forwardly and upwardly extending stationary alni 328 is bolted to the portion 124 of the machine frame. A lug 330, projecting laterally from the gripper arm 322 has a thumb screw 332 threaded into it. The opstanding end of the arm 328 is so e done by inserting the pin 172 located that, when the machine is at rest and the screw 332 properly adjusted, the gripper jaw 320 will be held a short distance away from the nose of the wiper 258. A spring pressed pin 334,*bearing against the front of the carrier 240 tends always to move the jaw 32 toward the wiper 258.

In use the wor is located against the jaw 320 as a stop, in the manner previously described, the upwardly projecting edge of the upper being inserted between the wiper 258 and the gripper jaw 320. As the wiper carrier 240 moves forward, after the machine is started, the spring pressed piu 334 keeps the point of the screw 332 against the stationary arm 328. Since the pivot 324 is moving forward, the jaw 320 will move backward toward the advancing wiper A258. The wiper and the jaw 320 thus form a gripper, which seizes the upper at about the time that the advancing wiper comes into .engagement with it.- Further advanceof the carrier 240 causes the screw to leave the stop arm 328 and the edge of the upper is held in the gripper by the tension of the spring behind the pin 334. The' upper is drawn tightly against the last, being tensioned both by the advance of the gripper and by the action of the wiper 258 which forms one jaw of the gripper. `During; the final portion of the advance of the gripper and wiper mechanism the ljaw 320 may slip off the work, which is at that time held securely by the downward pressure of the wiper. The return movement of the mechanism justy described is effected in the same manner as heretofore set forth.
